The St. Jude's Ranch for Children will take your used cards and recycle them into new cards to resell and benefit their efforts.

Why St. Jude's Ranch for Children?
"They rescue abused, abandoned and neglected children of all races and faiths from the vicious cycle of child abuse and provide healing and nurturing in a safe home-like environment where children can learn life skills to start new lives with new chances, new choices and new hope.
St. Jude’s Ranch for Children has three campuses in Nevada and Texas. The Bulverde, Texas campus is located in the Texas Hill Country just north of San Antonio. Also about 30 minutes north of San Antonio is St. Jude’s Emergency Children’s Shelter."
The Ranch also helps pregnant teen mothers through their pregnancy, supporting them physically with a residential facility and mentally with parenting curriculum and a high school education.

You can mail your cards yourself, or bring them to me and I will gladly include them in my package.
(They can not accept Hallmark, Disney or American Greeting cards.)
The Ranch also accepts Campbell Soup Labels for Education. Again, feel free to mail yourself, or send them to me and I will mail them for you. :)
